H/s ATTORNEY Patented July 18, 1933 UNITED STATES ANTON E. HANSON, OFCHICAGO, ILLINOIS WASHING MACHINE Application filed April 9,

This invention relates in general to machines for washing clothes, butmore in particular it has reference to a mechanically operated machinewhich provides a washing 5 machine for washing clothes in general, and

even the finest of fabrics, such as delicate lace and silk cloth,without the least danger of the goods being torn or injured, or ofcoming in contact with any moving mechanlsm.

An important object of the invention contemplates a washing machinewhich provides not only a machine for washing and cleaning clothes, butone wherein dishes may be washed and cleaned.

Another important object of the invention contemplates the provision ofa washing machine wherein the washing liquid is being forced back andforth, alternately, in an upward and downward motion through theclothes, and slightly changing the position of the clothes during eachalternation, during the process of washing, so as to thoroughly wash andclean every article which may be in the process of being washed.

Another important object of the invention contemplates the provision ofa washing machine wherein provision is being made whereby the washingfluid is being lifted, or pumped up, as it were, and spilled over thearticles in the machine and, simultaneously draw the fluid down and awayfrom the articlcs in an upward movement of an oscillating plunger and,on a reverse movement of such plunger, force such downwardly drawn fluidback in an opposite direction and against the articles. In such mannerof washing, and of the movement of the Washing fluid, the articles, suchas they may be, are being kept continually agitated to the extent thatevery particle of such articles are being continuously subjected to theswirling back and forth motion of the washing fluid, resulting in athorough washing and cleaning of the articles in, comparatively, a verysmall space of time.

The invention further contemplates the provision of a washing machinehaving a 0 pair of oppositely oscillating paddles, or

pumping devices, which work, in the manner 1931. Serial No. 528,849.

of apump,in an oscillatorymotion in opposite extended curved spacesbeing enclosed by inner and outer curved walls and end plates comprisinginner and outer Walls of the washing machine. The spaces being spacedapart by a central partition disposed longitudinally of the machinebetween the inner and outer curved walls and extending to the end platesalong the bottom of the machine. The spaces, however, being left open attheir upper extremity, and through such opening the washing fluid isbeing spilled, alternately, first through one and then through theother, over distributer plates and over the articles being containedwithin the inner curved 65 walls. The inner walls having a multipleseries of spaced perforations arranged in parallel rows throughout theirlength and spaced a distance out from the central partition. Throughsuch perforations the washing fluid is being pumped back and forth,during the process of washing, by means of said pumping devices.

The invention further contemplates the provision of a pair ofoscillating pumping paddles, or pumping devices, being so arranged as towork simultaneously but in opposite directions of each other so as topump the washing fluid alternately up and down through the articlesbeing washed to the extent that such articles are being 'keptcontinually agitated back and forth in every direction so that everyparticle of such articles is being thoroughly washed through theswirling action of the washing fluid.

The invention further contemplates the provision of mechanism forsimultaneously operating a pair of oppositely arranged pumping paddles,or pumping devices, in an oscillatory motion in contra-direction of eachother. It further contemplates the provision of, comparatively, a verysmall fractional horse-power motor to operate a washing machine of theabove construction and of a size suitable for household use. In suchhousehold machines a one-sixth t) horsepower motor will be amplysufficient. Therefore, providing quite a saving in the cost of operatingsuch machines in homes.

The invention further contemplates the provision of a collapsible standfor supporting a washing machine, of my construction, to any suitableand convenient height above the floor and over a sink whereby the samemay be drained. It further provides a stand which may be folded togetherand the whole apparatus be stored in, comparatively, a very smallont-of-the-way place, as, for instance, in a small closet, or under atable. And, even, the machine may be of such size that it, and the standtherefor, may be stored under a bed.

The invention further contemplates the provision of a washing machinehaving inner removable parts which may be removed from time to time forcleaning the interior of the machine and, for making repairs, ifnecessary.

The invention further contemplates a washing machine of the abovedescription which is comparatively simple of construction and having aneat pleasing outward appearance, and which may be manufactured at,comparatively, a very small cost.

The invention further contemplates the provision of a cover for themachine which provides a hollow drainboard whereupon washed goods, asmay be taken from the wash. may be placed and the surplus water andmoisture removed from them by means of suction or vacuum being producedwithin the cover.

These and other objects of my invention will be better understood byreferring to the several illustrations in the accompanying drawings, andwill be more fully described in the following specification, and moreparticularly pointed out in the appended claims.

Illustrated in the accompanying drawings;

Figure 8 is a detail of the mechanism, comprising a pumping plunger. forcirculating the washing fluid in the machine; and

Figure 9 is a detail of the mechanism, comprising a pumping plunger, asbeing employed in the modified form of my invention, for circulating thewashing fluid in the machine.

Similar characters refer to similar parts throughout the several views.

In the main, my invention comprises, substantially, a pumping devicewherein cloth abric, and even dishes, may be thoroughly cleaned bypumping the washing fluid, which may be contained within the machine,over the goods and forcing it upwardly and downwardly through the goodsto the extent that the goods (cloth, etc.) as having been insert-edthrough top opening 63, and deposited in the basket 20, are being keptcontinually agitated and turned to expose every particle of the goods,such as cloth fabric, to the circulating action of the fluid.

To illustrate my invention I have shown in the drawings a washingmachine comprising an outer frame or casing 10, enclosing inner andouter walls 11 and 12 respectively. The inner and outer walls beingspaced apart, preferably in the manner indicated in Figures 3, 4-. 5.and 6, to provide space in which to operate a pumping plunger 13, or,14.

In order to support the washing machine at various heights, or to storeit away in an out-of-the-way place, a collapsible stand 15, is providedand attached to the machine preferably in the manner indicated inFigures 2, 3, and A locking device 16, being provided whereby the stand15, may be securel locked from collapsing from any position to which itmay be arranged.

In the present con:--:tructi(m of the machine, sides 17 and '18, arecurved to form a pair of curved walls concentric with each other oneither side of the longitudinal center of the machine. \Valls 17, beingpreferably formed into two identical halves having flanges 15) formedtherein. Upon these flanges is supported a coarse mesh wire frame orbasket- 20. The halves being joined together, as at 19, by welding.Also, the upper and lower longitudinal edges of 17, are flanged over asat 21 and 22. The. upper and lower longitudinal edges of 18, beingflanged in the manner indicated at 23 and 2 1. Flanges 24, being joinedtogether by welding, as is indicated at 25. Flanges 24, being so formedas to provide a. groove 26, and a longitudinally extending dividing wallor partition 27, centrally between opposite curved spaces 28.

Referring to Figures 3, 4, and 6, it will be seen that walls 17, have aseries of inclined deflectors 29, formed therein by shearing out aportion of the material leaving openings 30, through which the washingfluid is being pumped during the operation of said plungers. In as muchas the deflectors are inclined in the same general direction, the fluid,on being pumped, takes a course also in the same general directionwhereby, during the process of washing, the goods, such as cloth, arebeing kept constantly moving around from one position to that of anotherso that every particle of the goods is being thoroughly washed.

Walls 17, are provided with end plates or walls 31, as seen in Figures3, 4, and 5, or, with end plates or walls 32, as seen in Figure 6. Theend plates being flanged over to form ofl'set portions 33, which areadapted to extend to end plates or walls 34 and 34, 35 and 35', andthere fastened as by means of screws 36, so that inner walls 11, may beremoved at any time for cleaning. Walls 31, 32, 34, 34, 35 and 35 being,preferably, welded to their respective walls 17 and 18. The lower edgeof plates 34, 34', 35 and 35' being bent out, as at 37, and flangeddown, as at 38, to form offset portions and means for fastening walls 11and 12 to the outer frame or casing 10. The walls being preferablyfastened together by means of rivets 39.

As will be seen in Figures 3, 4, 5. and 6, walls 11, are similar inform. Being constructed so facilitates their being readily assembled ordisassembled.

To flanges 21 and 23, is secured a guard and distributer plate 40. Itbeing fastened in place by riveting to flange 21, and by bolting it toflange 23, as is indicated in Figures 3 and 6. Formed in said plate 40,are a series of openings or apertures 41, and outstanding bars 42, andan inclined distribute!" plate 43. As the washing fluid is being pumpedup through the spaces 28, by the plungers 13 or 14, it flows out throughthe openings 41, and over plate 43, and onto the goods being washed.

In the sectional views, Figures 3, 4 and 5, is shown the arrangement ofa pair of pumping plungers having the form substantially of that shownin Figure 8. But, in the modified form, as shown in Figure 6, a plungersubstantially like that shown in Figure 9, is used instead. However, theprinciple of the operation of the two styles of plungers is the same.That is, as one of the plunger bars is being moved in an upwarddirection, the other is simultaneously being moved in an oppositedirection, so that, in either case, when the plungers are beingoperated, the washing fluid is being alternately pumped up throughspaces 28, first on one side and then on the other. And, as the upwardlymoving plunger is lifting the fluid up and through openings 41, itsimultaneously draws the fluid from the inner frame or receptacle 11,through the openings 30. But, on the downward movement of said plunger,the fluid, as having been drawn out through openings 30, into the space28, is being forced back through said openings 30, and into thereceptacle 11. And, since the deflectors 29, incline in the same generaldirection on either side of partition 27, the incoming fluid is therebybeing deflected toward one side of the receptacle 11, causing a swirlingmotion of the fluid, which effects a general stirring up of the washfrom one side of said receptacle to that of the other. The operation ofspilling the fluid over the wash and forcing it back and forth in anupward and downward motion through the goods being washed effects athorough cleaning of the goods in the wash in a comparatively shortspace of time without in the least danger of causing any injury of thegoods even though they may be of the most delicate of fabrics.

In the arrangement of the driving mechanism for the style of plungersshown in Figure 8, and as installed in the manner indicated in Figures3, 4 and 5, an intermediate driving gear 44, is being employed andarranged between two opposite intermeshing gears 45. Said gear 44, beingmounted on a stud 46, which, is, preferably, mounted on end plate 34, byspot welding it in place. Said gears 45, l'iowever, are being fastened,as by a key pin 47. to shaft 48, which extends through a packing gland49, and into an arm 13, of plunger bar 13, and there fastened as by akey pin 50. Directly opposite said shaft 48, and in line therewith, ismounted a bearing pin 51. and fixed in the manner indicated in Figures 4and 5. to provide a bearing for the opposite end of plunger 13, and. inlike manner, for plunger 14. Instead of having a pair of separateplungers of the style indicated in Figure 8, to work in space 28, it maybe desired to have such style plunger as shown in Figure 9. Theoppositely arranged plunger bars of which being connected at their endsto a pair of arms 14; formed in the manner substantially as shown inFigures 6 and 9. Vith such style plunger 14. it is only necessary toemploy not more than two operating gears. Main driving gear 44, however,being mounted on shaft 46, out from the longitudinal vertical center ofthe machine, as is indicated in Figure 7, instead of on its center, aswhen style plungers 13 are being used. Driven gear is instead, mountedon a shaft 48'. which extends, in a like manner to shaft 48, through apacking gland 49, and into arm 14 at its axis 52. Shafts 46 and 46 areeach being provided with a collar 53, having a key pin through it, withwhich to hold gears 44 and 44 in place.

Provided on gears 44 and 44, is a crank arm 54. It being connected inthe usual manner to a connecting link 55, which, in turn, is connectedto a crank 56, being mounted on driven shaft 57, of a speed reducingmechanism 58. Said mechanism 58, being preferably driven by an electricmotor 59. Ihe arrangement and setup of same being indicated in theseveral views, Figures 2, 4, 5 and 7.

To drain the washing fluid from the machine, a pipe connection 60, isformed between a valve or faucet 61, and the spaces 28. It may be herestated that, for large commercial machines, a pumping device forautomatically filling and emptying the machine may be provided, but, forhousehold devices, as here illustrated, such additional mechanisn'i andexpense would hardly be warranted.

In order to maintain the Washing fluid at a desired ten 'ierature duringthe process of *ashin electric heating units, 62, may be installed inthe position indicated by dotted lines in Figures 3 and 6.

Over an opening 63, as formed by flanges 23, and end walls 34 and 34,,35 and 35, is provided a hollow cover or closure 64, the same beinghingeably mounted as at 65. On the inside of said cover 6%, are provideda multiple series of perforations 66, through which moisture may draintrom the washed goods when the same have been taken from the wash andplaced on the cover when the same is opened to an inverted position asin.- dicated by dotted lines in Figure The cover ha a. lifting handle67. provided thereon and fastened in place as by spot welding. Formed inthe top of the cover, and on its longitudinal center, is a. conicaloutlet opening 68. the same being located. as shown in Figure 5, adesired distance from the axis of hinge pin 69. Said opening 69, beingprovided with a removable cap 70, which may be locked in place as in themanner ot a bayonet.

llqual to the distance of opening 66, From the axis of pin 6t), and inline with said opening, and on said center, is provided, in the top ofcasing 10, a flanged conically shaped drain outlet 71, which is providedwith a pliable seat 752, and a removable cork or stopper 73. At thelower end ot said outlet 71. is fastened, as by spot welding, a benttube 74, whereby connection may be made to a suction pinup through adoor opening 75, being provided in the nd ot casing 10, as shown inFigures 4 and 5. Said opening 7!), being provided with a door or hingedclosure 76. which may be locked closed by means of a padlock 77.

The operation of washing being conipleted. cover 64, is opened to itsinverted position bringing opening 66, in cooperative relation withoutlet 71. and forming a tight joint with pliable seat 72. The coverbeing arranged in this position and the washing placed thereon,substantially all the moisture being in the goods may be removed bymaking connection with tube 74, to a suction pump.

Tube 74, may be arranged in the position as indicated by bent tube 74',whereby the surplus moisture in the goods placed on the cover may drainback into the machine.

Having thus described my invention, it can be readily understood thatthe minor details of its construction may be altered in several wayswithout departing from the spirit and scope of the invention, andwithout losing any of its attendant advantages.
